Smart rings with NFC

NFC

— wireless communication technology at short distances (up to 10 cm). One of the most popular uses of NFC is using a ring for contactless payments. The function actually turns the device into an analogue of a credit card with a chip and allows you to pay without once again removing the card from your wallet or pocket. Another common function is to simplify Bluetooth connection with a smartphone or tablet that also has NFC: instead of manual setup, just bring one device to another - they will automatically recognize each other and establish a connection; all that remains is to confirm the connection. Other methods of interaction may also be provided - for example, reading NFC tags, selecting the operating profile of a paired smartphone, sending a business card, etc.
